The FIMC camera node wrapper is not a bus, so using simple-bus fallback compatible just to instantiate its children nodes was never correct. Drop the simple-bus compatible and expect driver to explicitly populate children devices. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> --- Changes since v1: 1.
